Hi
SDRAM can run programs normally when using W9825G6
But when using W9864G6, it will enter MemManage_Handler error when halfway through execution.
The two SDRAM W9825G6 (256Mb) W9864G6 (64Mb) in addition to the difference in capacity, there is a difference in one foot, the former has A12 pin, the latter is NC pin
W9825G6
W9864G6
The code is executable to start, but after using W9864G6 to start FreeRTOS vTaskStartScheduler(), it will enter MemManage_Handler error, W9825G6 will not
The SDRAM size has been changed to 64Mb in the setting
Which setting still needs to be modified? Please assist in processing, thank you!

From your MCUXpresso IDE setting: RAM1 size 0x600000 - 48Mb.
MemManage fault is always caused by incorrect MPU setting or wrong RAM region access
